SPECIFICATION forming part of Letters Patent No. 435,569, datedSeptember 2, 1890.

Application filed May 17, 1890. Serial No. 352,186. (No model.) Patentedin England October 29, 1889, No. 17,037.

To ctZZ whom it may concern.-

Be it known that I, CLARENCE M. STINER, a citizen of theUnited States,residing in New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Locks, (forwhich I have received Letters Patent in England, No. 17,037, datedOctober 29, 1889,) of which the following is a specification.

In my United States patent, No. 413,794, dated October 29, 1889, I haveillustrated and described avloclgwhich is adapted to insure theperformance of o neact or dutysuch as the turning off of water in abuilding at nightbefore another act or dutysuch as the lock-ing of thefront door of the same building-can be performed, and to said patentreference may be had for ageneral and detail statement of the mainpurposes and advantages of the invention. Apparatus based on the samegeneral idea may also be used to compel the performance of a greaternumber or series of acts; and the production of such apparatus is theobject of my present invention.

My invention consists in the construction and combination of parts, ashereinafter de scribed and claimed.

In the accompanying drawings, Figure 1 is a perspective View of thelock-holder with the lock and key inserted therein. Fig. 2 is aperspective view of the lock removed from the holder. Fig; 3 is aperspective view of the inner walls of the lock. Fig. 4 is a verticalsection of the lock, taken on line 4 4 of Fig. 8. Fig. 5 is a sideelevation of the lock with one side wall removed. Fig. 6 is a verticalsection on line (3 (5 of Fig. 8. Fig. 7 isa detail View of the pin-key.Fig. 8 is a plan of the lock and holder. Fig. 9 is a perspee tive viewshowing the lock in operation, and Fig. 10 is a similar view from theother side of Fig. 9.

M represents the lock casin g or shell, which may be placed adjacent toa cook or valve in the same manner as illustrated in my patent referredto. The shell M is provided with opening m, corresponding with the largeopening 1) in shell B, and With a small hole m corresponding with theslit 0. The lock itself is made of a shape to fit within the shell, andis provided with a key-shaft o, the upper end of which is adapted toreceive the key X. To this shaft is pivoted four tumblers o 0 o 0. Thetumbler o is tight on the key-shaft and is provided with a bolt orprojection 0', which, when the said tumbler is thrown, extends acrossthe opening 0 in the lock. This opening 0 is in line with opening anwhen the lock is in the shell M. Each tumbler is provided with aspring-bolt p, which, when the tumblers are in the position or planeindicated in Fig. 8, extends into and engages with cavities in the frontwall of the look, as shown in Fig. 0. The tumblers are therefore lockedin that position. The front wall of the lock is perforated at points popposite the bolts p, as shown, so that by means of a pin-key (shown inFig. 7) the spring-bolts 1) may be thrown back to release the tumblers.

One of the side walls of the lock is fitted with four springs q q q q,as shown in Fig. 3, which bear against the sides of the four tumblersand tend to swing them on their pivots.

On the opposite sides of the tumblers and" connected therewith areplaced a series of lugs r '2' r and s s s. The lugs r are in the form ofbrackets. The lower one is secured to the lower tumbler and extendsupward into the plane of movement of the second tumbler. The next lug isconnected to the second tumbler and extends up into the plane ofmovement of the third tumbler, and so on. The series of lugs s s s arearranged in exactly the same way as the lugs r 'r 0; but the lugs r "rr, as before stated, are slightly offset or formed like brackets, sothat the tumblers to which they are attached may have a slight limitedmotion with respect to the others. The springs q q q q bear against thatside of the tumblers carrying the lugs r r 0'. As before stated, theupper tumbler is tight on the key-shaft. \Vhen the key is inserted inthe lock and the upper tumbler is turned thereby in the direction of thearrow, Fig. 8, and to the position indicated by dotted lines, all of thetumblers will be carried with it until they are brought up against thesprings q and the spri11gbolts p p p 19 drop into the notches on thefront wall of the casing. This looks all of the tumblers and preventsthem from moving back until they have been released, locks the key inplace, and also withdraws bolt o from the opening 0 Owing to bolt o andlocking the valve.

the position of the lugs with respect to the tumblers, it will beobserved that it is necessary to release the bolts 1) in exactsuccession, beginning with the lower one. NVhen the lower bolt 1) isreleased, the spring q, bearing upon the tumbler, swings the tumbler aslight distance on its pivot until the bolt is out of the notch. Thisslightmovement of the tumbler is permitted on account of the offsetconstruction of the lugs r 0- r. The next tumbler may now be releasedand moved in the same manner, and so on throughout the seriesoftumblers,it being necessary to release the lower one first and theothers successively, as before observed. If it should be attempted torelease the second tumbler first, it is evident that it could not beaccomplished, inasmuch as the lug s on the lower or first tumbler wouldprevent the lower spring g from forcing the tumbler over.

In describing the operation of this apparatus let us consider, forexample, that the operations to be enforced are the locking of threewindow-shutters, turning oif the water, and locking of the front door.One of the pin-keys Q, shown in Fig. 7 must be attached to or connectedin some manner with each of the shutters Q and with the handle of thewater-cock. Then the lock 0, with the key X held in it, is carried toone of the Windows and placed in a seat 0 in the proper position toreceive the pin-key Q in the lower perforation p of the lock when theshutter is closed. The act of closing the shutters, as illustrated inFigs. 9 and 10, therefore releases the lower tumbler. The lock may thenbe removed and carried to the next shutter and the same operationperformed to release the second tumbler, and so on, until all three ofthe shutters have been locked and the three tumblers released. The lockis then carried to the lock-holder M and inserted therein. Thislock-holder is located with respect to the cock-handle substantially asshown in my patent referred to, and the cock-handle will be providedwith a keeper having loops to enter the opening 'm. The water is thenturned off and the cock-handle carrying the keeper forced into theopening m. At the same time a pin-key like that shown in Fig. 7,connected with the cock-handle, also penetrates perforation m in thelock-holderM, which is in line with the upper hole p in the front wallof the lock and releases the upper tumbler. All four tumblers are nowreleased and thekey may be turned, thus throwing over Key X may now beremoved and used to lock the front door.

I have mentioned the shutters and valve simply as an instance; but it isquite obvious that the locking of any combination or number of doors,windows, gates, shutters, hatchup ways, handles, levers, &c., may beassured by simply fitting them with the proper keys, lock-holders, &c.,in accordance with the principle herein referred to. Each seat-YO, it wll be noticed, is pivotally connected with 11's support, as at 0". Thisis to enable said seat to be swung, so as to allow the removalof thelock after the shutter or other similar device has been closed andfastened, as by its latch g Having now particularly described acertained the nature of my said ,inve and in what manner the same is tobe t formed, I declare that what I claim is 1. In alock, a plurality oftumblers, mfeol bination with two series of lugs, the lugs ing connectedwith the tumblers in sucl manner that one of the tumblers cannot-1nwithout carrying all the others with it.

2. In a lock, a plurality of tumblers, late. to prevent the movement ofthe tumblers, devices or keys connected with a pluralit; gates or barsfor releasing the respect.

latches for the purpose set forth. 3. In a lock, a key-shafu'in'em witha plurality of tumblers, all but one of which are loosely pivotedthereto, latches to prevent the movement of the tumblers, lugs to insurethe movement of the loose tumblers when the tight one is thrown, andkeys or other devices connected with a plurality of gates or bars forreleasing, successively and respectively, the latches, for the purposedescribed.

4. In alock, the combinaiion,with aseries of pivoted tumblers and acorresponding series of springs bearing against the same, of latches forlocking said tumblers and means connected with a plurality of gates orbars for releasing, respectivelyand successively, the said latches.

5. In a lock, the combination, with a series of pivoted tumblers and acorresponding series of springs bearing against the same, of latches forlocking said tumblers, lugs constructed and arranged to permit of alimited movement of the tumblers under the action r of the springs, andmeans connected with a no plurality of gates or bars for releasing,respectively and successively, the said latches.

In witness whereof I have hereunto atfixed my name in the presence oftwo subscribing Witnesses.
